Description

Technical Field

[0001] This utility model relates to the field of fumed silicone rubber technology, specifically a feeding mixer for fumed silicone rubber production. Background Technology

[0002] Fumed silicone rubber is a high-performance organosilicon elastomer made by mixing silica, prepared by the fumed method, with raw silicone rubber and other additives as the core reinforcing filler. Its core characteristic is the use of a reinforcing filler prepared by the fumed method, which endows the material with superior comprehensive properties, making it an important raw material for high-end silicone rubber products. A dedicated feeding and mixing machine is required during the processing of fumed silicone rubber. For example, Chinese patent (publication number: CN220003629U) discloses a feeding and mixing machine for silicone rubber production. This machine includes: a support frame with a base at the bottom and a support frame at the top; a feeding mechanism including a feeding cover slidably connected to the support frame via a lifting mechanism, and a mixing tank adapted to the feeding cover and installed on the base; the outer wall of the feeding cover has several inlets, and a corresponding feed pipe is installed outside the inlets; and a mixing mechanism for mixing the material in the mixing tank, including a mixing rod rotatably connected to the feeding cover and several mixing blades installed on the lower outer wall of the mixing rod. This device facilitates the addition of different materials during the mixing process, preventing impurities or dust from being introduced due to excessive contact with air during feeding and mixing. This results in cleaner feeding and mixing, preventing contamination of materials during addition and ensuring uniform mixing, making it highly practical. However, while this patented solution achieves the aforementioned anti-contamination effect, it fails to effectively improve the mixing efficiency, preventing users from fully mixing the materials in the mixing tank and thus affecting the processing quality of fumed silicone rubber.

The bottom of the positioning spring 37 is fixedly connected to the top of the cover plate 36, and the top of the positioning spring 37 is fixedly connected to the bottom of the lifting cross plate 31.

[0017] refer to Figure 2 The lifting mechanism 2 includes a bracket 21, which is fixedly connected to both sides of the top of the base 101. A motor 22 is fixedly connected to the top of the bracket 21. The output end of the motor 22 passes through the bracket 21 and extends into the interior of the bracket 21, where a threaded rod 23 is fixedly connected. A threaded sleeve 24 is threadedly connected to the surface of the threaded rod 23. A lifting block 25 is fixedly connected to the inner side of the threaded sleeve 24. The inner side of the lifting block 25 is fixedly connected to the lifting cross plate 31. An inertial synchronizer is installed on the motor 22 to enable the motor 22 to rotate synchronously. The threaded rod 23 and the threaded sleeve 24 are high-precision threaded rods and sleeves to reduce errors and prevent unexpected failures caused by errors in the threaded rod 23 and the threaded sleeve 24.

[0018] As a technical optimization of this utility model, by setting up a lifting mechanism 2, the stability of lifting is ensured. The fixed connection between the lifting block 25 and the lifting cross plate 31 can precisely adjust the stirring depth of the stirring blade 34, adapt to the stirring requirements under different feeding amounts, and improve the adaptability of the equipment to the gas phase silicone rubber production process.

[0019] refer to Figure 1 The base 101 has four support legs 4 at its bottom corners, and the top of the support legs 4 is fixedly connected to the four bottom corners of the base 101 via flanges.

[0020] As a technical optimization of this utility model, by setting the support leg 4, the height of the equipment can be raised, making it easier for operators to maintain the bottom of the base 101; at the same time, the flange connection makes the installation and disassembly of the support leg 4 more convenient and enhances the stability of the equipment placement, avoiding the mixing effect of the gas phase silicone rubber raw material due to shaking during stirring.

[0021] refer to Figure 2 The bottom of the mixing tank 102 is fixedly connected to an inverted T-shaped circular plate 5, the bottom of which penetrates the base 101 and extends into the interior of the base 101.

[0022] As a technical optimization of this utility model, by setting an inverted T-shaped circular plate 5, a stable limit can be formed on the mixing tank 102, preventing the mixing tank 102 from shifting due to material impact during the mixing process, thereby improving the mixing uniformity and equipment operation safety.

[0023] refer to Figure 3 Fixed bearings 6 are fixedly connected to the top and bottom of the threaded rod 23, and the outer ring of the fixed bearing 6 is fixedly connected to the inner wall of the bracket 21.

[0025] refer to Figure 3 The inner side of the bracket 21 is provided with a sliding groove 7, and the interior of the sliding groove 7 is slidably connected to the surface of the lifting block 25.

[0026] As a technical optimization of this utility model, by setting the sliding groove 7, the lifting trajectory of the lifting block 25 can be precisely guided, preventing the lifting block 25 from deviating or tilting during movement, ensuring that the lifting cross plate 31 and the stirring blade 34 always remain vertically lifted, avoiding collision with the inner wall of the mixing tank 102, and further improving the uniformity of mixing.

[0027] The working principle and usage process of this utility model are as follows: In use, the fumed silicone rubber raw material to be stirred is added into the stirring tank 102. The inverted T-shaped circular plate 5 at the bottom of the stirring tank 102 penetrates the interior of the base 101, ensuring the stable placement of the stirring tank 102 on the base 101. Simultaneously, the sealing plate 103 on the front of the base 101 is inserted into the base 101, limiting the side of the stirring tank 102 and preventing lateral displacement during stirring. Then, the motor 22 at the top of the bracket 21 is activated to drive the threaded rod 23 to rotate. The threaded rod 23 drives the threaded sleeve 24 to move downwards. The threaded sleeve 24 drives the lifting block 25 and the lifting cross plate 31 fixed thereto to descend synchronously. During the descent, the cover plate 36 in the sealed lifting stirring mechanism 3 first contacts the top of the stirring tank 102. As the lifting cross plate 31 continues to descend... The limiting rod 35 slides upward relative to the lifting cross plate 31, the positioning spring 37 is compressed and generates elastic force, so that the cover plate 36 fits tightly against the top of the mixing tank 102, thereby sealing the mixing tank 102 and reducing the contact between the raw materials and the outside air. Then the motor 32 is started, and the output end of the motor 32 drives the stirring rod 33 and the bottom stirring blade 34 to rotate, stirring the raw materials in the mixing tank 102. At the same time, the lifting mechanism 2 drives the threaded rod 23 to rotate back and forth through the forward and reverse rotation of the motor 22, so that the threaded sleeve 24 drives the lifting block 25 and the lifting cross plate 31 to move up and down back and forth. During this process, the stirring rod 33 and the cover plate 36 remain in sliding connection, and the stirring blade 34 moves up and down synchronously with the lifting cross plate 31. The rotation action is combined to achieve comprehensive stirring of raw materials at different heights in the mixing tank 102, avoiding dead zones in the stirring.

[0028] In summary, this feeding mixer for fumed silicone rubber production, by setting up a sealed lifting mixing mechanism 3, wherein the cover plate 36 is connected to the lifting cross plate 31 through the limiting rod 35, and with the elastic force of the positioning spring 37, the cover plate 36 can be tightly fitted to the top of the mixing tank 102, significantly improving the sealing of the mixing process and reducing the mixing of impurities caused by the contact between the fumed silicone rubber raw material and the outside air; at the same time, the mixing rod 33 is slidably connected to the cover plate 36, ensuring that the mixing blade 34 always fully mixes the material in the mixing tank 102 when it rises and falls with the lifting cross plate 31, avoiding mixing dead corners, improving the uniformity of raw material mixing, and ensuring processing quality.
